4. A rectangular bedroom has a perimeter
of 42 feet. If the length of the bedroom is
11 feet, what is the width of the bedroom?

Answer 1

Answer: The answer to to this question is 15.3 feet

Answer 2

the width of the bedroom is 9ft

since we know the length is 11, we know that on both sides of the rectangle, it’s 22 in total

42 - 22 would equal the width combined

42 - 22 is 20

in order to only find one side, we must divide 20 by 2, which is 10

this means that the width of the bedroom is 10 :)
